Privacy Preservation of Image Data With Machine Learning
An explanatory n-dimensional number vector represents an example of an item, which aids pre-processing and data methods. Feature vectors are frequently weighted to build a predictive function to measure the prediction's quality or fitness. Various feature reduction approaches, such as main component analysis, multi-liner subspace decrease, iso maps and latent semantic analysis, can lower the dimension of a feature vector. Functional space is frequently referred to as vector space.
